西门子S7-200 与opc软件KEPServerEx的 通讯设置过程(Siemens S7-200 communication set-up process)

说明：  MATLAB GUI上位机，WiFI通信，连接稳定，可同时采集四个通道的数据，互不干扰(Matlab GUI upper computer, WiFi communication, stable connection, can collect data of four channels at the same time, without mutual interference)

串口调试小程序，很不错的小例子，有详细代码描述，适合初学者(Serial debugging applets very good example)

串口调试助手，适合做串口通讯的人员使用。VB.NET编程。(vb.net serial debug for usart comm.)

实现串口通信功能。由中断程序调用，实现串口单字节读写的功能。(Realize the serial communication function. By the interruption of the procedure call, the realization of single-byte read and write serial port function.)

说明：  简单的串口通讯例子，有主机，目标机组成，发送数据，接受数据(Simple example of serial communication, a host, target composition, send data, receive data)

MSComm控件串口通信编程，第一次作业。(MSComm control serial communication programming, the first operation.)

串口调试助手，适合做串口通讯的人员使用。VB.NET编程。(vb.net serial debug for usart comm.)

串口函数，蛮好，测试过的，值的一看，用了才知道好。(Serial port functions just fine, tested, value a look, used to know better.)

串口读写，基于labview做的，可以实现上位机与下位机调试用(Serial reading and writing, based on labview do, you can achieve the PC and the next crew debugging)
